4 Claims.

The present invention relates to seat structures and `more particularly to seats which are especially well'adaptedfor installation in buses, airplanes, motor cars and railway coaches.

The primary objects of the instant invention are to provide a seat of the character above indicated which is light in weight yet rugged and sturdy in construction; to provide such a seat which is attractive in appearance; to provide such a seat which is comfortable in use; to provide such a seat which is economical in manufacture; to provide such a seat whose parts, upholstery and the fastenings thereof cannot engage the clothing of persons occupying'or moving to or from the seat and injuring the same; and, to provide such a seat which may be readily and conveniently constructed and assembled.

Illustrative embodiments of the invention are shown in the accompanying drawing, wherein: Figure 1 is a front elevational view of a seat structure of the character hereinbefore set forth; Figure 2 is a side elevational view thereof; Figure 3 is an enlarged fragmentary sectional View on line 3--3 of Figure 2; Figure 4 is likewise an enlarged fragmentary sectional View of a modified construction;

Figure 5 is also an enlarged fragmentary sectional view of another modified construction; and

Figure 6 is a fragmentary front elevational View Y thereof.

Referring then to the drawing in which like parts of the seat structure shown are designated by the same numerals in the several views, a seat back support is here shown as comprising an inverted U-shaped tubular member I IJ whose generally vertically disposed legs II, I2 are forwardly and slightly upwardly fashioned and then laterally turned toward each other to form side supporting portions I3, I4 and a forward supporting portion I5 for the upholstered or cushioned seat I 6.

Arcuately shaped arms I'I, here shown as constructed from tubular stock, are preferably secured between the legs II, I2 and the seat supporting side portions I3, I4 in any suitable manner for reinforcing purposes and supporting legs I8, likewise here shown as formed of tubular stock and secured together in spaced upright position 5o by transverse reinforcing struts I9, 20, are provided and upon which the seat supporting frame is mounted in any suitable manner.

'I'he leg I I is provided with a pair of vertically spaced tongue or pin receiving apertures 2I disposed at an angle in Figures 3 and 4 and on the 1936, Serial N0. 86,454

inner sidethereof and the leg I2 is provided with a pair. of vertically spaced screw receiving openings 22.A

The upholstered seat back shown in Figures 3 5 comprises the rigid member 23 of wood or the like and hair or padding 24 forwardly thereof disposed within the enveloping cover member 25 of leather or other suitable material.

In Figures 3 and 4, the seat back is shown as provided with vertically spaced tongues 26 in the form of angularly projecting pins which register with and are inserted into the tongue receiving apertures 2| and vertically spaced securing elements 2l here shown as machine screws register with and extend through the screw receiving openings 22 and into the secured seat back plate 28 in fastened engagement therewith.

In Figure 5, the secured seat back plate 29 has an arcuately curved tongue portion 30 which extends into the tongue receiving apertures 2| and the other vertical side of the seat back (not shown) is secured in a maner like the seat backs in Figures 3 and 4.

A finishing seat back plate 3|, spot welded to brackets 32 which are secured to the seat back supporting legs II, I2 on their opposite inner sides, may be provided if desired and as shown in Figure 2.

It will thus be seen that the seat structure herein shown and described is light in weight yet rugged and sturdy in construction, is attractive in appearance and comfortable in use, is economical in manufacture and convenient of assembly and that the seating herein shown and described is especially well adapted for installation in buses, airplanes, motor cars and railway coaches.

While but several embodiments of this invention have been herein shown and described, it will be understood that certain details of the constructions shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims.

I claim:

1. In a seat structure of the class described, an

inverted U-shaped tubular seat back support, one ieg of said support having a forwardly and inwardly facing tongue receiving aperture therein and the other leg thereof having a forwardly and inwardly extending screw receiving opening therethrough, a seat back having a fixed rearwardly and outwardly projecting tongue tted within said aperture, and a securing screw extending through said opening and into the seat 'back in fastened engagement therewith, said seat back being in overlapping engagement with said seat back support.

2. In a seat structure of the class described, an inverted U-shaped tubular seat back support, one leg of said support having a forwardly and inwardly facing tongue receiving aperture therein and the other leg thereof having a forwardly and inwardly extending opening therethrough adapted to receive a securing element, a seat back having a i'lxed rearwardly and outwardly projecting tongue fitted within said aperture, a securing element extending through the said opening and into the seat back in fastened engagement therewith, said seat back being in overlapping engagement with said seat back support.

3. In a seat structure of the class described, an inverted U-shaped tubular seat back support, one leg of said support having a forwardly and inwardly facing tongue receiving aperture therein and the other leg thereof having a forwardly and inwardly extending opening therethrough adapted to receive a securing element, a seat back having a iixed rearwardly and outwardly projecting tongue tted within said aperture, a securing element extending through the said opening and into the seat back in fastened engagement therewith, said seat back being in overlapping engagement with said seat back support, and a finishing plate for said seat back secured to the seat back support.

4. In a seat structure of the class described, an inverted U-shaped tubular seat back support, one leg of said support having a forwardly and inwardly facing tongue receiving aperture therein and the other leg thereof having a forwardly and inwardly extending opening therethrough adapted to receive a securing element, a seat back having in its opposite side edges recesses respectively embracing said legs and having a xed tongue projecting rearwardly and outwardly from one of said recessed edges and fitted within said aperture, and a securing element extending through the said opening and into the other recessed edge of the seat back in fastened engagement therewith.
